Abstract
Root canal anatomy of mandibular second molars differs among individuals. With the aid of the latest dental technologies in endodontics, the present case report highlights the diagnostic tools required to confirm the morphology of the root canal, and the treatment of uncommon root anatomy of a single-canal single-rooted mandibular second molar. Clinicians should be aware of the various anatomic variations that each tooth may present in order to achieve a satisfactory result. Furthermore, in order to improve the quality of care delivered to their patients, practitioners must have the necessary knowledge and abilities to utilize the diagnostic and therapeutic instruments at their disposal.
Key Questions
What was the primary objective of the study?
The study aimed to assess the root and root canal anatomy of mandibular second molars with C-shaped root canal configurations in residents of the Hail district using Cone Beam Computed Tomography (CBCT). It also examined the impact of gender and side on the frequency of root canal morphology.
What methodology was used in the research?
The researchers analyzed 304 untreated mandibular second molars with fully developed roots from both right and left sides. CBCT was utilized to determine the root form and canal morphology for each root, based on Vertucci's classification. The prevalence of C-shaped root canal systems was also investigated.
What were the key findings regarding root and canal morphology?
Out of 304 mandibular second molars, 94.1% had two roots, while 4.3% exhibited C-shaped root canal systems. The most common root canal morphology observed was two canals in the mesial root and one canal in the distal root (69.4%). The overall prevalence of C-shaped root canal systems was 4.3%.
What conclusions were drawn from the study?
The study concluded that the patient's race significantly influences root canal anatomy. Notable differences in root canal morphology of mandibular second molars were observed among Saudi subpopulations. The majority of these molars had two roots and three root canals. The presence of C-shaped root canal systems should be considered during treatment.
